A “catastrophic sleep-loss epidemic” is causing a host of potentially fatal diseases, a leading expert has said.

In an interview with the Guardian, Professor Matthew Walker, director of the Centre for Human Sleep Science at the University of California, Berkeley, said that sleep deprivation affected “every aspect of our biology” and was widespread in modern society.

And yet the problem was not being taken seriously by politicians and employers, with a desire to get a decent night’s sleep often stigmatised as a sign of laziness, he said.

“Once you know that after just one night of only four or five hours’ sleep, your natural killer cells – the ones that attack the cancer cells that appear in your body every day – drop by 70 per cent per cent, or that a lack of sleep is linked to cancer of the bowel, prostate and breast, or even just that the World Health Organisation has classed any form of night-time shift work as a probable carcinogen, how could you do anything else?” …

Sleep apnea is a serious killer, even if one spends plenty of hours in bed.

I got fitted with a CPAP just 4 months ago, and it has changed my life. No more anxiety attacks. Much more alert and energetic. It would have saved my career, if I had been diagnosed 10 years ago.

Anyone with a habit of chronic snoring should mention this your doctor. If you have any vague complaints and just don't feel as sharp as you did years ago... It's not just getting older. It's more likely the cumulative affects of sleep deprivation. It can be treated.

Pretty much expected. There have been four definite GW events since 2015 plus one that was questionable. They all appear as stellar class Black Hole mergers. The last one was GW170814 so on August 14th this year. Did you feel it? A third detector, Virgo, in Italy detected that one as well. So now there are three observatories and that refines the location in the sky. Optical telescopes (both robot and human controlled) also responded as well but they found nothing in the optical spectrum.

The newly discovered compound combats cancer by triggering apoptosis–an important process that rids the body of unwanted or malfunctioning cells. Apoptosis trims excess tissue during embryonic development, for example, and some chemotherapy drugs indirectly induce apoptosis by damaging DNA in cancer cells.

Apoptosis occurs when BAX–the “executioner protein” in cells–is activated by “pro-apoptotic” proteins in the cell. Once activated, BAX molecules home in on and punch lethal holes in mitochondria, the parts of cells that produce energy. But all too often, cancer cells manage to prevent BAX from killing them. They ensure their survival by producing copious amounts of “anti-apoptotic” proteins that suppress BAX and the proteins that activate it.

Three days after the last Black Hole merger detected by the three LIGO observatories they detected a pair of neutron stars merging. And the event was detected in the E&M spectrum as well. These are a candidate for Gamma Ray Bursts (GRB) and space telescopes detected that (Fermi Space Telescope, European Integral) and optical telescopes on Earth detected the glowing remains of the merger. So there are two records of the event; the Gravitational Wave detection GW170817 and the GRB event GRB170817. So this is the first time anything like this has been detected and the two records mean some interesting physics is possible. This is the closest event at approx. 130M LYs away. The optical telescopes nailed the source as a bright new object in the galaxy NGC 4993.

It's just breaking as news now so stories are appearing as details become available.

It's pretty interesting phenomena. I wonder what will come from the assessment of the time difference between the one interferometer detection and the optical observation.

For a phys.org article they got a little liberal in some sloppy phrasing for phenomena associated with Relativity:

Evidence of this cosmic clash hurtled through space and reached Earth on August 17 at exactly 12:41 GMT, setting in motion a secret, sleepless, weeks-long blitzkrieg of star-gazing and number-crunching involving hundreds of telescopes and thousands of astronomers and astrophysicists around the world.
It was as if a dormant network of super-spies simultaneously sprung into action.

Exactly what time is it? And that's a writers prerogative but using "simultaneously" seems inappropriate

Wiki reference for quick summary:

In physics, the relativity of simultaneity is the concept that distant simultaneity – whether two spatially separated events occur at the same time – is not absolute, but depends on the observer's reference frame.

I think you may be more putting the wrong emphasis on "simultaneous". AFAIK the GW detection was first, so gravitational waves preceded the GRB arrival and it arrived at Virgo first, then LIGO LA, then LIGO WA, and seconds behind that was the GRB detected by Space telescopes. It might be that the LIGO detectors are equipped with monitoring that generates an alarm that starts calling and emailing people. I know that Fermi ST does send an alarm on GRB detection and the receiving systems do call people and robotic telescopes. That spread very quickly throughout the astronomical world. It would like many instruments and people in the astronomical world were all responding at the same time. And of course that is intended by monitoring systems calling and emailing them.

So now let's interpret the story...

It was as if a dormant network of super-spies simultaneously sprung into action.

So this is about the response on Earth with people and robotic telescopes following a very close sequence of GW & GRB events. It may be that a GW detection is now tied into an alarm and call out occurs for it too just as the GRB detection is. Is this all news to you?

As for the slightly delayed optical GRB I think the GW precedes the burst physically and also the space medium is not perfectly transparent to light as it is with GW. So some distortion and even slightly more delay for E&M phenomena may occur. This also occurs with Supernovae. The massive flux of neutrinos associated with collapse of the star into the core arrives many hours before the light of the supernovae at distances of 160K LYs. This was observed with SN 1987a, and they detected just that. When the CERN neutrino experiment seemed to claim that neutrinos traveled faster than the vacuum speed of light that would have also meant that the neutrinos for SN1987a should have arrived 3 years before the supernova light and they did not. This was one more piece of corroborating evidence that the neutrino timing in the CERN experiment was flawed.

My critique was on the word choice of the article writer-- not on the events. The article writer chose the word simultaneous within a simile ("it was as if")--- that seems like not a good fit for an article about relativity.

On the physics/detection side-- this is what I thought would be interesting to learn more about on the time difference:

The neutron star collision was different.

It generated gravitational waves—picked up by two US-based observatories known as LIGO, and another one in Italy called Virgo—that lasted an astounding 100 seconds. Less than two seconds later, a NASA satellite recorded a burst of gamma rays.

Less than 2 seconds... after the end of the 100s gravity wave or after the start? Or was it in the middle?

2 seconds after the end would make for some very interesting science study. Even 2 seconds difference-- what is the speed of the gravity wave pulse vs. the E&M observation (wave propagation at speed of light along the curve of space ).

You'll have to find the research publications, and there should be a bunch, to see the exact sequence timing. It's really not news reporting that would be a good source for exact timing. I haven't looked on Arxiv yet but nobody has referenced the pre-print server yet either. When most of the astro-physics world is called up I think there may be a bunch of publications.

A bunch more info on the August 17 Neutron Stars merger. Some of these are scientific journal articles/letters rather than reported news articles. Nothing yet has shown up on ArXiv on this event. So the larger articles are yet to come.

This was a spectacular rich event and really lit up the Astrophysics and Astronomy world. And there will be not only be more events like this but follow on analysis & papers of data from this event. There is a lot here. They all tried to keep it secret within a world wide community. There was a lot of crunching data until they had a shared view of what happened.

Receipt of red blood cell transfusion from female donors with a history of pregnancy was associated with increased mortality among male recipients; further research is needed to replicate these findings, determine their significance, and define the underlying mechanism.

...That doesn’t mean that time was running backwards. But what the scientists saw happen between the two particles over time was the opposite of what you or I can expect in our ordinary lives...

Clickbait.

Nope, doesn't appear to be clickbait. Probably ends up in quantum computing. These are Qubits violating the 2nd law at will apparently and they're not entangled but their spin is correlated, I think. The second law presumes uncorrelated components in the system so what do you call this? It's real even if the exotic interpretation seems a little strained. But how do you define the arrow of time (think of it as evolution in time LOL!)? They think they can do this with larger systems as well.
